colivnYrNG Application :filed September Beit knownttnat, FRED' E. SCHWALB, a resident of Chicago, Illinois, have invented a certain'new and useful Improvement'in Conveying Apparatus, of which the following is a specification. i

rlhis invention relates to conveyors in gen# eral, but moreY particularly to those em.- ployed in handling coal, and especially to the apparatusemlployed for transferring the coal from vcars to places of storage, or to wagons or other means of transportation.

(enerally stated, the object" of the inven tion is to provide an improved portable conlveyer which can 4be moved intojposition to receive the materials thereon, and which can,

' be shifted O ull of the Way when it is desired -to move the .cars or-oth`er portable receptacles from which the coal `or other materials are discharged onto the'conveyer, so thatthe latter can be' used for'successively unloading' the'materials from' a series of cars standing on a track. f l 1 It is also an object toprovide certain details and features-of construction and cornbinationsl tending to increasel the general efficiency andthe desirability of a zconveyer of this particular character.

, To these and other useful ends the inventionconsists in matters hereinafter set' forth and clamedand shown in the accompanying drawings, in which- `Fig. 1 is a side elevation of aportable conveyer embodying the principles ofthe invention, Yshowing the hopper body of the coal car in cross section, and showing the track in cross section, with the said conveyer disposed vin position to receive the coal from the said hopper body of the car. 'g

s thus illustrated, the invention lcomprises side bars or sills 1, preferably of channelfiron, suitably connected together byvend bars 2 to for'm a rectangular frame. frame is mounted on, wheels 3 which are car ried by axles 4 mounted in blocks 5 which slide up and down .in the guides, handp screws being provided for the adjustment Y This; as previously stated. Thehand screws 7 are APPARATUS.

supported in any Vsuitable manner, it being l observed that that it is adapted to receive the coal or other materials from .the said car. This plate reciprocates endwise, and for this purposeis supported by Wheels 13 that travel in the channel virons 1 of the body frame. Skirt boards 14 are hinged to the body frame at 15, and a similar end board 16 is also hinged -to the body frame, thereby forming a sort of hopper to receive the discharge of the coal or other materials from the car. A shaft 1'7 is suitably mounted transversely on the body frame, near the end thereof, and is ,provided 'with crank devices by pitinen 19 with the plate 11, whereby the latter` is reciprocated back and forthA endwise, other materials to gradually work along to- .yvard the edge 20 of the reciprocating plate, and to then fall upon the defiector 21 and .frointhe'latter u on the conveyer belt 22 that leads to the p deliver thecoal or other materials. Ai rno'toi` 23 is suitably connected with the shaft 17 to drive the latter .at the desired speed. Swinging props 24 are provided to hold the boards 14 and 16 4in raised position, it being understood that these boards and said y A props are adapted to fold over flatwise upon the conve er when not in use. After tiie cars havebeen shifted to vbring onej of the hopper-like bodies opposiite the rails 8, the unloading apparat-us isthen such reciprocation causing the coal or ace where it is desired tov A horizon- 8 which are connected 11, and conveyed by the reciprocating inotion of the latter to the point of discharge,

adjusted, preferably, until the side members 1 of the rectangular body frame rest upon the rails 9 of the main track, so that these rails will sustain the weight of the mateof theaXles up andfdown in said guides, so rials discharged fromthe car. Inasmucliy as that the body frame canbe' raised and lowthe boards 14 and 16 prevent the materials ered at will.' Said wheels 3 travel on rails 8 'from' spreading in three directions only, it

. follows that the materials can spread in the fourth direction, toward the edge 2O of the reciprocating conveyer plate, and the back andV forth motion of the 'said plate causes the materials to gradually shift along until they fall upon ther deflector 21 and from the latter upon the belt conveyer 22 by which the coal or other materials are carried upwardly to a point where they are then discharged into a wagon or into another car, or into any desired receptacle, or upon the ground. After the materials are all discharged and carried away from the car, the latter is then shifted and another car is brought into position, it being understood that the hand screws 7 are adjusted to raise the conveyer body frame from the track rails, so that the entire apparatus can be pulled away from th'e rails 9 to permit the shifting of the car on the main track. As soon-as another loaded car is in position, the unloading apparatus is then pushed back over the rails of the main trac-k, and the hand screws 7 are adjusted to again lower the rectangularbody frame upon the rails of the track and the unloading operation is then repeated. In this way, an apparatus is provided for .conveying the co`al directly from the car to a wagon or other car, orA otherwise, as stated, without the necessityV of constructing deep loading pits and storage bins for the coal, and in a way that per-v mits rapid and easy .unloading of the cars, one after the other, for the desired purpose, such 'as in handling coal or any other materials which can be handled and conveyed by the apparatus shown and described. The belt conveyer 22 may be of any suitable character, ofcourse, but is preferably adapted to be movedl so that it may be taken out of the way when it is desired to roll the conveyer or feeder having the wheels 3 along the rails 8, when the apparatus is shifted either toward or away' fromj the car.

lThe lower end of this belt conveyer may be disposed in a shallow recess or pit formed in the ground', as shown in- Fig. 1; but it will be understood that the means for carrying the materials away from the apparatus may be of any suitable, known, or approved form.

VWhat I claim as my invention is l. A portable conveying apparatus comprising a body frame, a reciprocating feeder supported by said body frame, means for supporting said body frame to extend transversely of a car track to enable said feeder to receive the discharge from a car, and mechanism adjacent the outer end of said frame to reciprocate the feeder in a horizontal plane to produce a shifting movement of the materials thereon, with a discharge space between said feeder and ysaid mechamsm.

2. A structure as specified in claim 1, said 1 ,carece means comprising wheels for said body frame, together with rails on which said wheels travel, oneend portion of said body frame and reciprocating feeder being adapted to overhang the rails of said car track, so as to extend under the car which discharges from the bottom thereof, means to hold the discharge on the feeder, means to raise and lower said body frame, so that the body frame maybe lowered to rest upon the rails of the car track belowY the car, and means for receiving and carrying away the discharge from said reciprocating feeder.

3. A structure as specified in claim l, one end portion of said bodyl frame and reciprocating feeder being adapted to overhang the rails of said car track, so as to extend below a car which discharges from the bottom thereof, in combination with means for lowering the body frame onto said rails.
